A connecting passage and pipe gallery will be constructed to join the basement level of the Digester Control Unit and the thermophilic digesters. The construction of a new tunnel section that will connect the basement level of Digester Control Unit and the existing tunnel system. Within this new tunnel section will be an airlock to maintain physical separation between new and existing facilities to comply with current code. The removal of the existing Digester Complex 901 flare and construction of a new flare. The construction of a new Cogeneration (CoGen) Building that will house two 2,500 kW, dual fuel engines with heat recovery. The three existing CoGen engines that are located in Digester Complex 900 will be demolished along with associated mechanical, process, electrical structural and architectural components. All remaining associated electrical components in the existing north control room in Digester Complex 900 will be relocated to the new Digester Complex 900 MCC Room. Site excavation and grading will be performed, and a new site drainage system will be constructed on the northern part of the plant site.
